BATTERY-HANDLAMP.

To all whom it may concern Be it known that 1, Lonnw. MAISEL, a citien ot the United States, residing at Madison, in the county of Dane, State of lVisconsin, have invented certain new and useful Improvements in Battery-Handlamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will nable others skilled in the art to which it appertains to make and use the same.

The present invention elates to battery hand lamps, and more rticularly to that type in which the lamp 18 protected from shock or impact or other undue pressure by the battery.

The objects and advantages of the present invention will be mad clear by the following d tailed description, taken in conjunction with the accompanying drawings, wherein- Figure shows a complete battery candle: c is a section through a hand lamp comp-rising a battery candle to which a refiector and lens have been added to alter the distributit of light from the i1. :andescent lamp; and

ig. 3 is an end view of the structure shown in 1 with the lens, reflector and head removed therefrom.

In the particular embodiment illustrated in the drawings the battery comprises a plurality of dry cells 1 and 2 arranged end to end in series relation. and contained within the usual cardboard tube The naked bottom of the lowermost cell rests on and makes electrical connection with the coiled spring 4 carried by the metal cap 5. screwthrcaded to the lower end of a tube 6. forming the body ot the casing. This tube 6 may be of metal, as shown, or may be of hard fiber or other suitable material. At the front end of tube 6 and secured thereto, as by riveting, is a threaded collar 7. the front edge of which is preferably turned over to form a retaining flange 8.

At the front end of the casing. and preferably attached thereto permanently, as by being screw-threaded into collar 7 before the latter is riveted to tube 6, is a disk 9 of insulating material, such as fiber. serviceable as an abutment against which the top end of the battery bears and which it is firmly held by the pressure of spring l at the bottom of the case. An opening in the Specification of Letters Patent.

center of disk 9 accommodates the upper or carbon electrode 10 of the topmost dry cell.

Mounted on disk 9 is a conductor which may be in the form of a circular plate 11, fastened with nails 12, and having a curved integral linger 13 bent down into a slot in disk 9 to serve as a contact element cooperating with the curved front end 14 of a sliding linger 15 which can be manipulated in usual manner by a thumb button 16 mounted near the center of the casing.

Attached to conductor 11, as by soldering, is a spring 17, the upper end of which is soldered or otherwise fastened to the outwardly flaring edge of a support 18, into which is threaded or otherwise secured the base of an incandescent lamp 19. This spring 17 serves to conduct current from conductor 11 to one terminal of the lamp and holds the other or central terminal 20 of the lamp in yielding engagement with the top terminal 10 or" the battery.

With the several elements constructed and assembled as above described, the circuit is as follows from the upper battery terminal 10. through the lamp to its support or socket 18. thence through spring 17 to plate 11 and finger 1?), and thence by way of sliding finger 15. case (:3. cap 5 and spring at to the other ,termin al ot the battery. This structure, as illustrated in Fig. 1, is completely operative as a battery candle and gives a well distributed light. However. for the purpose of obtaining "from the battery lamp a relatively concentrated beam of light, there is provided an enlarged head having a threaded portion 21, screwed on to collar 7, and having a flaring portion 22 with a threaded cylindrical extension 23 terminating in a flange 24 on which the reflector and lens are seated. The usual threaded ring 25 holds the lens and reflector in place. The reflector 26 is not integral with the lamp socket or support 18 and, in fact. has no connection therewith. The opening at the center of the reflector is large enough to pass the lamp bulb and the lamp socket. and there is an air gap at 27 serving to insulate the reflector from the socket. for without this insulation the hand lamp. it otherwise constructed as shown in the drawings, would burn continuously.

Other objects and advantages of the construction described will be apparent to those skilled in this art, and changes in details of the several parts and in their grouping are contemplated within the scope of the invention as defined by the appended claims.
